1. Product Overview
The TELECO WFT402 is a versatile portable Wi-Fi router designed to provide internet connectivity using a SIM card. It supports GSM, 3G, 4G, and LTE signals, converting them into a Wi-Fi hotspot with a coverage area of approximately 30 square meters. This device is ideal for mobile environments such as cars, campers, boats, or small offices, thanks to its flexible power options (12V DC and 230V AC).
The WFT402 is a Category 4 router capable of supporting up to 4 devices simultaneously, including smartphones, tablets, smart TVs, and other Wi-Fi enabled peripherals. It features an internal antenna for good signal reception and includes two SMA ports for connecting external antennas to enhance signal strength.

3. Operation
3.1. Powering On/Off
- To Power On: Press the "ON/OFF" button located on the rear panel. The LED indicators on the front will illuminate.
- To Power Off: Press and hold the "ON/OFF" button until the LED indicators turn off.
3.2. LED Indicators
The front panel features several LED indicators to show the router's status:
- SYS: System status indicator.
- NET: Network activity indicator.
- RF: Radio Frequency signal strength (multiple bars).
- SIM: SIM card status.
- WIFI: Wi-Fi network status.
- WPS: Wi-Fi Protected Setup status.
- ETH1: Ethernet port status.

3.3. Connecting Devices via Wi-Fi
- Ensure the router is powered on and the WIFI LED is active.
- On your device (smartphone, tablet, laptop), search for available Wi-Fi networks.
- Select the Wi-Fi network name (SSID) broadcast by the WFT402 (usually found on a label on the router).
- Enter the Wi-Fi password (also found on the router's label) when prompted.
- Your device should now be connected to the internet.
3.4. Using the WPS Function
WPS (Wi-Fi Protected Setup) allows for easy connection of compatible devices without manually entering the password:
- Press the WPS button on the router (refer to the device layout for exact location). The WPS LED will start blinking.
- Within two minutes, activate the WPS function on your client device.
- The devices will automatically connect.
3.5. Accessing the Web Interface
For advanced settings and configuration, you can access the router's web-based management interface:
- Connect your computer to the router via Wi-Fi or an Ethernet cable (WAN/LAN port).
- Open a web browser and enter the router's default IP address (usually 192.168.1.1 or similar, check the router's label or manual for the exact address).
- Enter the default username and password (also found on the router's label or in the quick start guide).
- You can now configure settings such as Wi-Fi name, password, security protocols (OPEN/WPA-PSK/WPA2-PSK), firewall rules, and more.
4. Maintenance
4.1. Cleaning
To maintain optimal performance and appearance:
- Wipe the router's exterior with a soft, dry cloth.
- Avoid using liquid cleaners, aerosols, or abrasive materials.
- Ensure no dust accumulates in the ventilation openings.
4.2. Software Updates
The WFT402 supports software updates via TR069 and local update methods. Regularly checking for and applying updates can improve performance, security, and add new features. Refer to the router's web interface or the manufacturer's website for update procedures.
4.3. Resetting the Device
If the router experiences issues or you wish to restore factory settings, you can perform a reset:
- With the router powered on, locate the reset pinhole (often labeled "RST" or "Reset") on the rear panel.
- Use a paperclip or a similar pointed object to press and hold the reset button for approximately 5-10 seconds.
- Release the button when the LED indicators flash or the router restarts.
- The router will revert to its factory default settings, and you will need to reconfigure it.
5. Troubleshooting
- No Internet Connection:
- Check if the SIM card is correctly inserted and activated.
- Verify that the SIM LED is active and the 4G LED indicates a stable connection.
- Ensure there is cellular signal in your location (check RF signal strength LEDs).
- Restart the router.
- Slow Wi-Fi Speed:
- Check the cellular signal strength (RF LEDs). Weak signal will result in slower speeds.
- Reduce the distance between your device and the router.
- Ensure no obstacles are blocking the Wi-Fi signal.
- Consider connecting an external antenna for better reception.
- Limit the number of connected devices if performance is critical.
- Router Not Powering On:
- Verify that the power adapter is securely connected to both the router and the power outlet.
- Check if the power outlet is functional.
- Ensure the ON/OFF switch is in the 'ON' position.
- Cannot Connect to Wi-Fi:
- Double-check the Wi-Fi password.
- Ensure the WIFI LED is illuminated.
- Try restarting both the router and your client device.
- If you recently changed Wi-Fi settings, try resetting the router to factory defaults (see Section 4.3).
